Although the 27-year-old is yet to confirm her second pregnancy her father recently announced that she and her husband of one year Sam Cooper, are expecting another child, according to the UK's "This Morning" show.

"Yes, she is pregnant," Keith Allen said on the popular show.

Allen, who now goes by the last name Cooper after her 2011 wedding, is said to be "over the moon" about the pregnancy and new reports suggest that she is due in December.

"Lily has started telling friends and everybody in her close circle is so excited for her. It was a surprise but Lily and Sam are thrilled," a source told the Sunday Mirror UK.

"The pair of them have loved every minute of parenthood so far and wanted to expand their brood quickly. So it's great timing," the source added.

Allen and Cooper, 34, were left devastated in 2010 after they lost their first baby six months into the British singer's pregnancy. It is believed that she contracted a viral infection which caused her to suffer a pre-term delivery.

Allen was later hospitalized with septicemia, a dangerous infection characterized by the presence of bacteria in the blood, although eventually she was able to fully recover.

On Tuesday she was spotted dining out at London's Nobu restaurant where she strategically hid her growing baby bump with a large designer handbag. While it is unclear why Allen is reluctant to confirm her second pregnancy, some critics believe that her prior miscarriage has made her more cautious.
